How long do cake pans usually last?

I have a couple of 9 inch cuisinart that have lasted several years but haven't used them THAT much.

I just bought me a pair of 14 inch magic lines on CL. I paid about $6 for both. The lady I bought them from did cakes and was selling some of her supplies. They have normal wear and tear but they're in 1 piece. Just wondering when you know that your pans are done.

Oh and I'll be baking in the MLs for the 1st time TONIGHT!

The 8" Wilton pans I own were bought over 10 years ago. They still work fine!

You pans are "done" when they are dented or warped. Effectively, when the surface of the pan leaves marks on the surface of the baked cake that you have to fix ..

I have cake pans that I inherited from a selection of relatives and friends that are 25-35 years old. As long as you look after the pan - no banging, no poking, no over-heating etc, and no shoving them in the cupboard - they should last a life-time.

This does not account for "surfaced" pans eg non-stick etc..

I have a pair of 9 inch round pans I bought nearly forty years ago at a cake supply store. I have no idea as to their brand but barring a small amount of discoloration they look brand new. Like Auzzi I have pans that I inherited from my grandmother and mother. Treat them well and they will last several lifetimes.

Ok- the ones with the non- stick surface, those I kill within a 2 years.
